A clear description on how to connect a RFID reader to a Arduino and output the unique ID of a RFID tag that is placed in close proximity to the antenna.

I may have to use this

This program is pretty much the simplest possible to check that the RFID shield and reader are working. It prints the tag number (in hex) of the RFID tag if one is present, otherwise it prints a #.Once you have uploaded it to the Arduion, switch to Serial Monitor, set at 57600 baud.
